What was the video supposed to prove? Did it have a point?
What it demonstrates is how the ancients may have perceived what they saw and how they reacted to seeing flying vehicles, and might explain why there are so many references to flying machines in the form of artefacts art and scripture throughout ancient history.
Let's look at technology for a minute. I've mentioned Nikola Tesla, who should be a household name imo because with out his work I seriously doubt we would be where we are today in regards to technological advancement, but he died penniless and pretty much forgotten about despite the fact he was thee greatest inventor of his time and quite famous for his demonstrations. If Tesla's greatest work had been realised, today there is no telling where mankind would be and we'd have stopped using fossil fuels at least 80 years ago.
If Tesla was able to harness and use such technology, is it so hard to believe that the ancients did too given that advanced are we as today can't replicate some of their achievements? I've been skeptical believe me, but it was after reading a book called Gods Of The New Millennium about 10 years ago that changed my whole outlook on whether aliens had actually visited Earth and built the pyramids or was it really man that built them, but using advanced technology, because we must have been far more advanced in ancient times than what we've been led to believe, because the context just doesn't fit the evidence.
Look at Edward Leedskalnin's "Coral Castle" and the secrecy he went to to conceal it, was he using similar energy to what Tesla demonstrated? Could he have wanted to protect his discovery for fear of going through a similar fate to Tesla?
Look at the "Hutchinson Effect" (see vid), had Tesla and Leedskalnin already discovered and perfected it, and is it just possible that the Sumerians 6000 years ago were the first to discover, harness and use such technology, because if they were, then what else were they capable of?
That's quite a leap to make considering how stylized their animal art was...
That's one way of looking at it, but when you look at other artefacts from around the same time depicting animals you can tell what they are because of the realistic detail and they don't stray far in artistic terms.
